Last fall I had a soil test performed prior to installing my lawn (new construction). I needed 50 lbs/1000 lime and 0-46-0 at 9 lbs/1000 which I tilled into the soil and then put down 10-6-4 at 10 lbs/1000 when I seeded the KB-rye-red fescue seed. Some sections of the lawn are still really thin so I am going to aerate and overseed again this fall. I just used a generic soil test to test the soil and even though I followed the recommendations last year, the soil looks to be as deficient in phosphorus as last year and and the pH looks to still be at about 6. My question is, could I use the recommendations from last years soil test this year using the 0-46-0 triple superphosphate on my existing turf without killing it. I heard that the 0-46-0 can kill existing turf. My other thought is to use Lesco starter fert with 50% slow release at a double rate to get 1.5 lbs of N/1000 and 2 lbs. P/1000 when I overseed and put down lime and then follow-that up later in fall with the labeled rate of starter fert. Any thoughts? Should I get another soil test?
